Application:
• Floor System:
It's much suitable for the floor plate of factory, workshop,
warehouse, etc.
• Roof System:
Solving the problem of roof leakage, reducing the use of roof
beam-column and improving security.
• Interior Partition System:
It has been widely applied to interior partition of high-rise
buildings, with the advantages of excellent fire-proof, best
hanging force and easy installation.
• Exterior Wall& Villa:
It's widely applied to various modular house, low buildings,
apartment, villas, and city house, etc.
Composite:
Calcium silicate board(face panel) + Cement and EPS(core) + Calcium
silicate board(face panel)
Advantages:
• Easy installation:
Easy to install, convenient for wire groove and water pipe inbuilt,
and casual for decoration.
• Shorten construction time:
For the same construction work, 3 workers can finish within
60minuts with this panel, while for traditional brick 12 workers 60
minutes.
• Saving space:
It can averagely increase extra 4.16 m2 area for100 m2 house.
• Saving cost:
Both labor cost and construction structure cost can be greatly
saved, for it's easy installation and light weight.
• Environmental protection:
raw materials do not include any harmful substances.
• High security performance:
It has higher anti-seismic and anti-impact performance than
traditional brick and other construction materials;
• Waterproof and Fire-proof
• Sound insulation
